Dog assist harness

ABSTRACT

This patent document discloses a harness for dogs with crippled hindquarters. The harness includes a sling for supporting the dog&#39;s belly near its hindquarters. A D-ring is mounted on each end of the sling. A rod-like handgrip for a human handler is detachably connected with the D-rings by snap-lock connectors. The inside layer of the sling that contacts the dog&#39;s skin comprises a launderable barrier fabric of polyester knit textile. The same material is used on the outside layer, but preferably only near the opposite end-portions likely to contact the skin or clothing of the handler. The mid-portion of the outer layer is of polypropylene since it does not normally contact the handler&#39;s skin or clothing. The sling of a second embodiment comprises a composite strap of nylon and sheepskin.

CLAIM OF PRIORITY UNDER 35 USC 119(e)

[0001] Applicant claims priority of Provisional Application No. 60/294,457 filed May 30, 2001, the entire disclosure of which is incorporated herein by reference, and made a part of the disclosure of this application.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] This invention relates generally to harnesses for dogs (and other four-legged animals), and is particularly concerned with harnesses for assisting dogs that have been crippled in their hind quarters by injury or disease. The invention is particularly concerned with the construction of a harness that can be utilized, with relative ease, by a human handler, to support the wholly or partially disabled hindquarters of dogs (of weights ranging from 20 to 200 pounds) for treatment by a veterinarian, for grooming, or to help the dog walk and exercise.

[0004] 2. Description of the prior art

[0005] Representative prior art U.S. patents in the relevant art include U.S. Patent Des. 330, 273 (Cernek-Oct. 13, 1992); U.S. Pat. No. 2,976,840 (Hugus-Mar. 28, 1961); U.S. Pat. No. 3,215,117 (Short-Nov. 2, 1965); and U.S. Pat. No. 4,375,203 (Parkes-Mar. 1, 1983).

SUMMARY OF THE INVENTION

[0006] It is not uncommon for pet dogs to become wholly or partially disabled in their hind quarters due to injury or disease. The injury may be either temporary or permanent with the dog being otherwise in good health. In either case, however, it is frequently necessary for a human handler to support the disabled hind quarters of the dog to permit the dog to exercise, to be treated by a veterinarian, to be groomed, and the like.

[0007] It is an object of this invention to provide a dog assist harness that can be quickly and easily installed to be utilized by a human handler to support the disabled hind quarters the dog for exercise, and other necessary activities of the type discussed in the preceding paragraph, and which can be easily and quickly removed from the dog.

[0008] A further object is to provide such a harness that can be utilized with minimum discomfort to the handler, and can also be cleaned and kept in a clean and sanitary condition with relative ease and efficiency.

[0009] The manner in which these, and other objects, are achieved, is set forth in the following description, with reference to the accompanying drawings.

DESCRIPTION OF THE DRAWINGS

[0010]FIG. 1 is a perspective view of harness for crippled dogs according to the present invention;

[0011]FIG. 2 is a sectional view of a portion of the harness taken on lines 2-2 of FIG. 1;

[0012]FIGS. 3 and 4 sequentially illustrate the installation of the harness on a dog by the handler;

[0013]FIGS. 5 and 6 illustrate the manner in which the harness is used to walk a dog; and

[0014]FIG. 7 illustrates an alternative construction of a harness for crippled dogs.

DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENT(S)

[0015] Reference numeral 1 (FIG. 1) collectively designates a harness assembly having, as its major components,(or sub-components) a sling assembly 3, and a manual lifting and control assembly 9 detachably connected with the ends of the sling assembly for transmitting lifting and turning forces from the human handler to the ends of the sling portion.

[0016] The sling assembly 3 comprises a belt or strap member 4 of flexible material capable of assuming a U-shape for receiving and supporting the belly of a dog near its crippled hind quarters (FIGS. 5 and 6) with the ends 5 and 7 located on opposite sides of the dog's torso.

[0017] The lifting and control assembly 9 comprises a handgrip 11 by which the handler manually applies lifting and turning forces to the ends 5 and 7 of the belt member 4 of the sling portion.

[0018] In the illustrated embodiment, the handgrip 9 comprises a wooden rod 11, and a pair of screw eyes 17 and 19 are mounted near the opposite ends of rod 11. A pair of conventional, double-ended, snap-lock connectors 13 and 15 detachably connect the screw eyes 17 and 19 to D-rings 21 and 23 projecting from the respective ends 7 and 5 of belt or strap member 4 of the sling assembly (FIG. 1).

[0019] The strap member 4 has an inside layer 25 (FIG. 1) for contacting the skin of the dog, and outside layer 27 that does not come into contact with the dog's skin in ordinary use. It is therefore highly desirable that the material of the entire inside surface 25 be of smooth, non-irritating, launderable material that can withstand numerous cycles of washing and drying while maintaining suppleness and impermeability. The preferred material for the inside layer, referred to sometime hereafter in this specification (and in the claims) as “Material A”, is the product identified in in the “Family of Launderable Barrier Fabrics from Vintex Inc.” in the “Style” column as “Heat Shield” having a weight in the “Total Weight: (oz/yd2) column of 12. The Heat Shield product is described in the “Product Features and Benefits” column as follows:

[0020] We added another durable polyester knit textile to the face of our 8/28 Product to “shield” the polymer barrier from high heat laundering conditions which could cause “fusing” of the polymer face in traditional barrier products . . . .

[0021] The Vintex Inc. documents discussed in the preceding paragraphs are attached to this application as Appendix A to this specification, and are incorporated, in their entirety, into this patent application as part of its disclosure so that any reference to “Material A” in this application will mean the Heat Shield product identified in the Vintex Inc. documents incorporated herein.

[0022] The outside layer 27 of a second material 29 that extends over a part of the length of outside layer, but less than the entire length (FIG. 1). The second material 29 is preferable of polypropylene. It does not come into contact with either the dog's skin, or with the clothing or skin of the handler during ordinary use of harness as illustrated in FIGS. 3-6. However, the portions 31 of the outer surface adjacent to the ends 5 and 7 of the sling portion do sometimes come into contact with the clothing and/or the skin of the human handler which makes it desirable to use Material A to shield the handler over the end portions of the outer surfaces as shown particularly in FIG. 1 by reference numeral 31.

[0023] The second embodiment shown in FIG. 7 is fully described in applicant's Provisional Application No. 60/294,457 which is attached hereto as Appendix B and forms a part of the disclosure of this application.
